The asymmetric unit of the title compound, C(9)H(7)N(3)O(2), is composed of two independent mol-ecules. The crystal structure is stabilized by C-H⋯O and C-H⋯N hydrogen bonds, forming a three-dimensional network. The crystal structure also features pyrazine-pyrazine π-π inter-actions [centroid-centroid distance = 3.6994 (5) Å] and also pyridine-pyrazine π-π inter-actions [centroid-centroid distance = 3.6374 (5) Å]. ...[more]

Ethyl 2-methyl-4-phenyl-pyrido[1,2-a]benzimidazole-3-carboxyl-ate.

Project description:The title compound, C(21)H(18)N(2)O(2), was synthesized using a novel tandem annulation reaction between (1H-benzimidazol-2-yl)(phen-yl)methanone and (E)-ethyl 4-bromo-but-2-enoate under mild conditions. The dihedral angles between the mean planes of the five-membered imidazole ring and the pyridine, benzene and phenyl rings are 0.45?(6), 1.69?(1) and 70.96?(8)°, respectively. In the crystal, mol-ecules are linked through inter-molecular C-H?N hydrogen bonds.

Ammonium 2-amino-pyrazine-3-carboxyl-ate.

Project description:The title compound NH(4) (+)·C(5)H(4)N(3)O(2) (-) crystallizes with two formula units in the asymmetric unit. In each anion, the carboxyl-ate is deprotonated and the planar amino group [angle sums of 359 (3) and 355 (3)° at N] remains protonated. In the crystal, the cations and anions are bridged by N-H⋯O and N-H⋯N hydrogen bonds, forming a three-dimensional network.

3-(4-Meth-oxy-phen-yl)pyrido[2,3-b]pyrazine.

Project description:In the title mol-ecule, C(14)H(11)N(3)O, the benzene ring is twisted by 14.0?(2)° from the plane through the fused ring system. In the crystal, ?-? inter-actions [centroid-centroid distances = 3.609?(1), 3.639?(1) and 3.735?(1)?Å] form stacks of mol-ecules propagating along the b axis. The crystal packing is further stabilized by weak inter-molecular C-H?O and C-H?N hydrogen bonds.

Acridinium 3-carb-oxy-pyrazine-2-carboxyl-ate.

Project description:The title ion pair, C(13)H(10)N(+)·C(6)H(3)N(2)O(4) (-), contains a protonated acridine cation and a 3-carb-oxy-pyrazine-2-carboxyl-ate monoanion, which are linked together through O-H⋯O, N-H⋯O and weak C-H⋯O hydrogen bonds. These hydrogen bonds generate a C(10) chain graph-set motif. The crystal structure is further stabilized by extensive π-π stacking inter-actions between nearly parallel [dihedral angle = 1.21(2)°] acridine systems. The shortest distance between the centroids of the six-membered rings within the cations is 3.6315 (8) Å. In addition, C-H⋯π edge-to-face inter-actions are present.

Poly[[hepta-?(2)-aqua-bis-(?(2)-pyrazine-2-carboxyl-ato)dibarium] bis-(pyrazine-2-carboxyl-ate)].

Project description:In the layered title coordination polymer, {[Ba(2)(C(5)H(3)N(2)O(2))(2)(H(2)O)(7)](C(5)H(3)N(2)O(2))(2)}(n), the coordination geometries around the two independent Ba(II) ions can be described as bicapped square-anti-prismatic [BaNO(9)] arrangements. A two-dimensional polymeric framework with (6,3) topology can be observed in the ac plane, the nodes being provided by Ba(II) ions and the connectors being N and O atoms belonging to pyrazine-2-carboxyl-ate ligands and O atoms of bridging water mol-ecules. Non-coordinating pyrazine-2-carboxyl-ate ions are located between the polymeric layers in the crystal and are interconnected through extensive O-H?N,O hydrogen bonding.

Crystal structures of 2,3-bis-(thio-phen-2-yl)pyrido[2,3-b]pyrazine and 7-bromo-2,3-bis-(thio-phen-2-yl)pyrido[2,3-b]pyrazine.

Project description:The crystal structures of 2,3-bis-(thio-phen-2-yl)pyrido[2,3-b]pyrazine, C15H9N3S2 (1), and 7-bromo-2,3-bis-(thio-phen-2-yl)pyrido[2,3-b]pyrazine, C15H8BrN3S2 (2), are discussed. Both mol-ecules crystallize in space group P21/c. In 1, the thienyl rings are inclined to the mean plane of the pyrido-pyrazine moiety by 6.16?(7) and 86.66?(8)°, where as in 2 the corresponding dihedral angles are 33.29?(11) and 19.84?(9)°. The pyrido-pyrazine moiety is relatively planar in 1 with the two rings being inclined to each other by 1.33?(7)°. In 2, however, the pyrido-pyrazine moiety is buckled with the corresponding dihedral angle being larger at 8.78?(10)°. In the crystal of 1, the packing creates inter-secting bilayers; the layering results from the pyrido-pyrazine moieties being engaged in offset ?-stacking, where the inter-planar distance is 3.431?(9)?Å with an offset 1.14?Å. In the crystal of 2, the mol-ecules pack head-to-head and are linked by a series of C-H?Br and C-H?N inter-molecular inter-actions, forming layers parallel to the ab plane.

Ethyl 3-(4-methyl-benzene-sulfonamido)thieno[2,3-b]pyridine-2-carboxyl-ate.

Project description:The thieno[2,3-b]pyridine ring system of the title compound, C(17)H(16)N(2)O(4)S(2), is essentially planar, the amino and carbonyl groups being nearly coplanar with the heterocyclic ring system. There are two N-H?O hydrogen-bonding inter-actions involving the same N-H donor set and two different acceptors, one in an intra-molecular bond helping to fix the mol-ecular geometry and the other defining a dimeric structure around the symmetry centre at (0, , ).

Project description:In the title mol-ecule, C(16)H(20)O(5)S(6), the two five-membered rings form a dihedral angle of 4.7?(3)°. The crystal packing exhibits weak inter-molecular C-H?O hydrogen bonds, which link the mol-ecules into chains propagating in [10], and ?-? inter-actions, indicated by the short distances [3.756?(5)?Å] between the centroids of five-membered rings from mol-ecules related by translation along the b axis.
